Experimental philosophy is a new interdisciplinary field that uses methods normally associated with psychology to investigate questions normally associated with philosophy. The present review focuses on research in experimental philosophy on four central questions. First, why is it that people's moral judgments appear to influence their intuitions about seemingly nonmoral questions? Second, do people think that moral questions have objective answers, or do they see morality as fundamentally relative? Third, do people believe in free will, and do they see free (...) will as compatible with determinism? Fourth, how do people determine whether an entity is conscious? (shrink)

Most people assume that, even though some degenerative or criminal behavior may be caused by influences beyond our control, ordinary human actions are not similarly generated, but rather are freely chosen, and we can be praiseworthy or blameworthy for them. A less popular and more radical claim is that factors beyond our control produce all of the actions we perform. It is this hard determinist stance that Derk Pereboom articulates in Living Without Free Will. Pereboom argues that our best scientific (...) theories have the consequence that factors beyond our control produce all of the actions we perform, and that because of this, we are not morally responsible for any of them. He seeks to defend the view that morality, meaning and value remain intact even if we are not morally responsible, and furthermore, that adopting this perspective would provide significant benefit for our lives.

There has been a long-standing dispute in the philosophical literature about the conditions under which a behavior counts as 'intentional.' Much of the debate turns on questions about the use of certain words and phrases in ordinary language. The present paper investigates these questions empirically, using experimental techniques to investigate people's use of the relevant words and phrases. g.

Robert Kane provides a critical overview of debates about free will of the past half century, relating this recent inquiry to the broader history of the free will issue and to vital currents of twentieth century thought. Kane also defends a traditional libertarian or incompatibilist view of free will, employing arguments that are both new to philosophy and that respond to contemporary developments in physics and biology, neuro science, and the cognitive and behavioral sciences.

The Metaphysics of Free Will provides a through statement of the major grounds for skepticism about the reality of free will and moral responsibility. The author identifies and explains the sort of control that is associated with personhood and accountability, and shows how it is consistent with causal determinism. In so doing, out view of ourselves as morally responsible agents is protected against the disturbing changes posed by science and religion.

Many philosophical problems are rooted in everyday thought, and experimental philosophy uses social scientific techniques to study the psychological underpinnings of such problems. In the case of free will, research suggests that people in a diverse range of cultures reject determinism, but people give conflicting responses on whether determinism would undermine moral responsibility. When presented with abstract questions, people tend to maintain that determinism would undermine responsibility, but when presented with concrete cases of wrongdoing, people tend to say that determinism (...) is consistent with moral responsibility. It remains unclear why people reject determinism and what drives people’s conflicted attitudes about responsibility. Experimental philosophy aims to address these issues and thereby illuminate the philosophical problem of free will. (shrink)

Skeptical worries about moral responsibility seem to be widely appreciated and deeply felt. To address these worries—if nothing else to show that they are mistaken—theories of moral responsibility need to relate to whatever concept of responsibility underlies the worries. Unfortunately, the nature of that concept has proved hard to pin down. Not only do philosophers have conflicting intuitions; numerous recent empirical studies have suggested that both prosaic responsibility judgments and incompatibilist intuitions among the folk are influenced by a number of (...) surprising factors, sometimes prompting apparently contradictory judgments. In this paper, we show how an independently motivated hypothesis about responsibility judgments provides a unified explanation of the more important results from these studies. According to this ‘Explanation Hypothesis’, to take an agent to be morally responsible for an event is to take a relevant motivational structure of the agent to be part of a significant explanation of the event. We argue that because of how explanatory interests and perspectives affect what we take as significant explanations, this analysis accounts for the puzzling variety of empirical results. If this is correct, the Explanation Hypothesis also provides a new way of understanding debates about moral responsibility. (shrink)

In this essay, I draw on Haidt’s and Baron’s respective insights in the service of a bit of philosophical psychoanalysis. I will argue that deontological judgments tend to be driven by emotional responses, and that deontological philosophy, rather than being grounded in moral reasoning, is to a large extent3 an exercise in moral rationalization. This is in contrast to consequentialism, which, I will argue, arises from rather different psychological processes, ones that are more “cognitive,” and more likely to involve genuine (...) moral reasoning. These claims are strictly empirical, and I will defend them on the basis of the available evidence. Needless to say, my argument will be speculative and will not be conclusive. Beyond this, I will argue that if these empirical claims are true, they may have normative implications, casting doubt on deontology as a school of normative moral thought. (shrink)

Incompatibilists believe free will is impossible if determinism is true, and they often claim that this view is supported by ordinary intuitions. We challenge the claim that incompatibilism is intuitive to most laypersons and discuss the significance of this challenge to the free will debate. After explaining why incompatibilists should want their view to accord with pretheoretical intuitions, we suggest that determining whether incompatibilism is in fact intuitive calls for empirical testing. We then present the results of our studies, which (...) put significant pressure on the claim that incompatibilism is intuitive. Finally, we consider and respond to several potential objections to our approach. (shrink)

Recent experimental research has revealed surprising patterns in people's intuitions about free will and moral responsibility. One limitation of this research, however, is that it has been conducted exclusively on people from Western cultures. The present paper extends previous research by presenting a cross-cultural study examining intuitions about free will and moral responsibility in subjects from the United States, Hong Kong, India and Colombia. The results revealed a striking degree of cross-cultural convergence. In all four cultural groups, the majority of (...) participants said that (a) our universe is indeterministic and (b) moral responsibility is not compatible with determinism. (shrink)

Joshua Knobe (2003a) has discovered that the perceived goodness or badness of side effects of actions influences people's ascriptions of intentionality to those side effects. I present the paradigmatic cases that elicit what has been called the Knobe effect and offer some explanations of the Knobe effect. I put these explanations into two broad groups. One explains the Knobe effect by referring to our concept of intentional action. The other explains the Knobe effect without referring to our concept of intentional (...) action. I discuss some problems with these explanations and conclude with some possible avenues for future research. (shrink)

In this paper we discuss studies that show that most people do not find determinism to be incompatible with free will and moral responsibility if determinism is described in a way that does not suggest mechanistic reductionism. However, if determinism is described in a way that suggests reductionism, that leads people to interpret it as threatening to free will and responsibility. We discuss the implications of these results for the philosophical debates about free will, moral responsibility, and determinism.

In this paper, I first review some of the recent empirical work on the biasing effect that moral considerations have on folk ascriptions of intentional action. Then, I use Mark Alicke's affective model of blame attribution to explain this biasing effect. Finally, I discuss the relevance of this research - both philosophical and psychological - to the problem of the partiality of jury deliberation. After all, if the immorality of an action does affect folk ascriptions of intentionality, and all serious (...) criminal offenses - e.g., murder and rape - are immoral in addition to being illegal, then a juror's ability to determine the relevant mens rea (i.e., guilty mind) of a defendant in an unbiased way may be seriously undermined.

Philosophers working in the nascent field of ‘experimental philosophy’ have begun using methods borrowed from psychology to collect data about folk intuitions concerning debates ranging from action theory to ethics to epistemology. In this paper we present the results of our attempts to apply this approach to the free will debate, in which philosophers on opposing sides claim that their view best accounts for and accords with folk intuitions. After discussing the motivation for such research, we describe our methodology of (...) surveying people’s prephilosophical judgments about the freedom and responsibility of agents in deterministic scenarios. In two studies, we found that a majority of participants judged that such agents act of their own free will and are morally responsible for their actions. We then discuss the philosophical implications of our results as well as various difficulties inherent in such research. (shrink)

An empirical study of people's intuitions about freedom of the will. We show that people tend to have compatiblist intuitions when they think about the problem in a more concrete, emotional way but that they tend to have incompatiblist intuitions when they think about the problem in a more abstract, cognitive way.

Knobe (2003a, 2003b, 2004b) and others have demonstrated the surprising fact that the valence of a side-effect action can affect intuitions about whether that action was performed intentionally. Here we report the results of an experiment that extends these findings by testing for an analogous effect regarding knowledge attributions. Our results suggest that subjects are less likely to find that an agent knows an action will bring about a side-effect when the effect is good than when it is bad. It (...) is further argued that these findings, while preliminary, have important implications for recent debates within epistemology about the relationship between knowledge and action. (shrink)

Claims about people's intuitions have long played an important role in philosophical debates. The new field of experimental philosophy seeks to subject such claims to rigorous tests using the traditional methods of cognitive science – systematic experimentation and statistical analysis. Work in experimental philosophy thus far has investigated people's intuitions in philosophy of language, philosophy of mind, epistemology, and ethics. Although it is now generally agreed that experimental philosophers have made surprising discoveries about people's intuitions in each of these areas, (...) considerable disagreement remains about the philosophical significance of the key findings. Some have argued that work in experimental philosophy should be assessed by asking whether it can contribute to the kind of inquiry that is normally pursued within analytic philosophy, while others suggest that work in experimental philosophy is best understood as a contribution to a more traditional sort of philosophical inquiry that long predates the birth of analytic philosophy.

Some theorists think that the more we get to know about the neural underpinnings of our behaviors, the less likely we will be to hold people responsible for their actions. This intuition has driven some to suspect that as neuroscience gains insight into the neurological causes of our actions, people will cease to view others as morally responsible for their actions, thus creating a troubling quandary for our legal system. This paper provides empirical evidence against such intuitions. Particularly, our studies (...) of folk intuitions suggest that (1) when the causes of an action are described in neurological terms, they are not found to be any more exculpatory than when described in psychological terms, and (2) agents are not held fully responsible even for actions that are fully neurologically caused.
